Exploration

Nampala Project, Mali

The exploration program in Nampala is progressing well. We plan to drill between 10,000 and 15,000 RC meters by the end of 2017. As a result, Innovexplo, which is in charge of this project, has arrived in Nampala for two months now. Their employees and collaborators first took note of all the exploration work that had been done over the last ten years and identified the existing drilling zones. In a second step, they developed a model to maximize the scope of planned drilling in the short to medium term. They are currently identifying the exact areas of drilling to be performed in the coming weeks accurately. The detailed exploration plan will be release as soon as it is available.
